How much laminate flooring do I need?

Measure your room length and width, multiply to get square footage, then add 5-15% waste allowance. Divide by the coverage per box to determine how many boxes you need. See also our find Total Area with Linear Feet to Square Feet Calculator.

What waste allowance should I use for laminate flooring?

Typically 10-15% waste is recommended for laminate flooring. Use 10% for simple rectangular rooms and up to 15% for complex layouts with cuts around obstacles.

How do I calculate square feet for flooring?

Multiply the room length by width in feet. For L-shaped rooms, break into rectangles and add them together. Subtract any areas that won't be covered like built-in cabinets.

Do I need underlayment for laminate flooring?

Most laminate flooring requires underlayment for moisture protection, sound reduction, and smoothing minor subfloor imperfections. Check if your laminate has attached underlayment.

How many planks come in a box of laminate flooring?

Laminate boxes typically contain 6-12 planks, depending on plank size. Check the manufacturer's specifications for exact count and square footage coverage per box.

What is the standard size of laminate flooring planks?

Common laminate plank sizes are 48-60 inches long and 5-8 inches wide. Luxury laminate planks can be up to 84 inches long and 12 inches wide for a more realistic wood appearance.

Should I buy extra laminate flooring?

Yes, always buy 1-2 extra boxes beyond your calculated needs for future repairs, manufacturing variations, and installation mistakes. Store extras in a dry location.
